The UCC27311A-Q1 is a robust gate driver designed to drive two N-channel MOSFETs in a half-bridge or synchronous buck configuration with an absolute maximum bootstrap voltage of 120V. Its 3.7A peak source and 4.5A peak sink current capability allows the UCC27311A-Q1 to drive large power MOSFETs with minimized switching losses during the transition through the Miller Plateau. The switching node (HS pin) can handle negative transient voltage, which allows the high-side channel to be protected from inherent negative voltages caused by parasitic inductance and stray capacitance.
The inputs are independent of supply voltage and are able to withstand -10V and +20V absolute maximum ratings. The low-side and high-side gate drivers are matched to 4ns between the turn on and turn off of each other and are controlled throught the LI and HI input pins respectively. An on-chip 120V rated bootstrap diode eliminates the need to add discrete bootstrap diodes. Undervoltage lockout (UVLO) is provided for both the high-side and the low-side drivers which provides symmetric turn on and turn off behavior and forces the outputs low if the drive voltage is below the specified threshold.
